Potassium isotope has a half life of 1.37 × 10 raise to 9 years and decays to an isotope of Argon which is stable.In a particular sample of moon rock the ratio of potassium atoms to Argon atoms was found to be 1:7 .Therefore the age of Rock assuming that originally there was no Argon present is?

Dear student
 
after every half life, number of potassium isotopes becomes half of its initial value, then after 4 half lifes, the number of potassium isotopes becomes 1/8 of its initial number.
 
Please let me know if this is correct then only I will share complete solution.
